At the commencement of the relationship, the Narcissist is a dream-come-true. He is often intelligent, witty, charming, good looking, an achiever, empathetic, in need of love, loving, caring, attentive and much more. He is the perfect bundled answer to the nagging questions of life: finding meaning, companionship, compatibility and happiness. He is, in other words, ideal.
It is difficult to let go of this idealized figure. Relationships with narcissists inevitably and invariably end with the dawn of a double realisation. The first is that one has been (ab)used by the narcissist and the second is that one was regarded by the narcissist as a disposable, dispensable and interchangeable instrument (object).
The assimilation of this new gained knowledge is an excruciating process, often unsuccessfully completed. People get fixated at different stages. They fail to come to terms with their rejection as human beings -- the most total form of rejection there is.
We all react to loss. Loss makes us feel helpless and objectified. When our loved ones die -- we feel that Nature or God or Life treated us as playthings. When we divorce (especially if we did not initiate the break-up), we often feel that we have been exploited and abused in the relationship, that we are being "dumped", that our needs and emotions are ignored. In short, we again feel objectified.
